5-0 out of 5 stars Very good for Statistics and Finance too...
I saw many reviewers for advanced math and engineering. I just want to add that it is also very good for stat and finance. It can be calculated with almost (I'm saying this because I haven't tried every single one yet ;-) every calculation with this TI-89. The plus side is that it has bigger screen and we can change any value anytime without starting over... especially good for multiple problem solving.

At first, I intendeded to purchase TI-BAII+ required by the professor but decided to trade this TI-89 Titanium with my old original TI-89. Both has flash applications for Statistics with List Editor and Finance as well as Data/Metrix Editor. For finance, you can get PV, FV, i, PMT, NPV, IRR, etc.

You can also download guide books from TI's website. This is a life saver for most business classes.... I used TI-89 from advanced algebra, pre- and calculus, fin & managerial accounting, economics, 2 statistics, and financial management... 10 courses altogether ;-) And this IT-89 cost about the same price of a business text book! Of course, you'll need to know the concepts and how to use this calculator first.

If you're wondering which one to choose between original TI89 and this new Titanium, I recommend original if you've vision problem. Original TI89 has deep purple and dark blue colors for "2nd" and "diamond" keys. This new one has very pale blue and light green keys, hard to look at if you need combination keys. SO do for the fonts and "alpha" key. As the manufacturer mentioned, this one has more memory and can be used USB cable.

Just a tip for the two reviewers below and others about fraction and decimal switching (.25 - 1/4 switching) :
Reviewer:MaxiMinerand Reviewer:cool dude (Stockholm)

Just use a "period" between the calculation (if you have all whole numbers) and you'll see decimals in the result without changing the "mode" you preferred. If you have any decimals between the calculations, you'll automatically see decimals. It works for every graphing calculator. I got that tip from a Math Lab Asst. in my algebra lab.

5-0 out of 5 stars Printed manual IS available
Well, it's just a "short" 606 page version for the TI-89/TI-92, but it still beats dealing with 900+ pages from Titanium CD or on-line manual.
Go to epsstore ti com Manuals/Guidebooks under TI-89 and get it for the measly 20+ (seems French and Spanish reading public gets 50% break).
Functionally TI-89 and TI-92 are nearly identical (minus keyboard on TI-89), so you can find very nice books on TI-92, like those from Gilmar publishing, that you can apply to your Titanium.
I had the same gripes as "cool dude" (see review below) about .25 - 1/4 switching until I started working in the exact mode, pressing [diamond][ENTER] (instead of just [ENTER]), when decimals are needed.
Still, if I need to work with fractions and other simple things, I pull out my trusty Sharp EL-506WBBK. To switch from .25 to 1/4 and back you just toggle with the [a b/c] key.
To get a proper function on TI-89 you have to envoke F2,7,2ND,(-),),ENTER. On Sharp: 2ndF, [a b/c].
But then again, Titanium is crafted for much finer things. And how it does them is beyond praise.

4-0 out of 5 stars Great Calculator - small print
This calculator seems to do everything and do it well. My only complaint is that the alternate key functions are somewhat hard to read and the screen can be somewhat hard to read. As you can guess I use glasses. I wish TI would make a screen where the fonts size can be adjusted and perhaps even a backlit screen, otherwise a great product.

4-0 out of 5 stars Tig Class
This Calculator is perfect for advanced math classes. It does more than I could ever believe. The Calculator is simple to use and has a nice screen format. The main problem is that it has so much processes that you actually have to dig got the x radical sign. It can even graph in 3-d. The only thing better is one that has a colored screen.

4-0 out of 5 stars Just a few things....
Perhaps Im little more whiny than you jankees, because I live in Sweden and had to pay almost the double price, since Im not allowedorder it from Amazon. Some complains:

The numbers on the screens are very small, compared to ti-83 for example. I wish their size could have been adjustable.

There are no simple method to get a number fractioned, like make 0.25 into 1/4. You have to go to the mode menue and switch to "exact". Its irritating, on ti-83 you just chose "frac". Maybe Im missing something so if its possible on this I want to know! :P

It just got natural and 10 logarithms. In matlab you can have log2 for example.

Otherwise, this is a really good and flashy calculator that makes all the ordinary ti-83/86 owners go like: " what is that?!". D-) ... Read more

5-0 out of 5 stars Very good product
This calculator is probobly the best one that i have owned. You can create graphs with it, you can do equations, you can even do complex algebra/trigonometry/calculus on this calculator. Also, for the kids, there are games that you can download quite simply of the internet for you to play in case by any chance you get bored during math class. (Don't get any bright ideas!) I know this product is very expensive, but it is well worth it once you realize how good this product actually is. Do yourself a favor, and buy this product!

5-0 out of 5 stars great calculator
I found this to be a useful calculator in high school.It definitely helped me see a lot of functions and perform experiments.

5-0 out of 5 stars The gold standard for calculators
I purchased my TI-83 Plus in 1999 and still have it today. I have never had any problems with it and can only remember changing the batteries 3 or 4 times. I've even dropped it from my 2nd story balcony by accident (more like a friend knocked it off a table on the balcony) and it didn't break. When I turned it on after it fell, my calculations were still on the screen!

It is easy to use and fast enough for all high school and college mathematics.

I'd recommend it to anyone who needs a workhorse of a calculator.

5-0 out of 5 stars Amazing
This is a fantastic calculator that I use in my algebra class and others.You can take notes on this calculator with the Ti keybord acsseorie the acsseorie comes with a program for the calculator so you can take notes on it and save them for tests. You can also store things like study cards,games,and all those other important things you need. I highly recommend this calculator to anyone with any class.GO GET THIS CALCULATOR!=)

5-0 out of 5 stars Too simple?I think not!
I looked at other more "fully featured" calculators for my daughter and decided against them.It is so easy to buy more than you need in calculators and end up with something too complex/confusing for purpose.Avoid the "my calculator has got more buttons thatn your calculator" syndrome.Better to buy a more complex one in three years for college, if needed - when they will be cheaper and have even more feaures. ...

5-0 out of 5 stars A word on documentation
Recently received my Voyage 200, and am very pleased with the unit itself. As others have commented, the lack of a decent printed manual is a drawback.

Knowing that the TI-89 Titanium is functionally almost identical to the Voyage 200, I called Texas Instruments and ordered a TI-89 manual. Customer service was very friendly, the manual was cheap ($4.95 + s/h), and it arrived quickly.

TI really should package this manual with the Voyage 200, and maybe they'll start doing it in the future. In the meantime, if you're getting a Voyage 200, just order an 89 manual from TI.

4-0 out of 5 stars Missing many statistic functions from TI-83
Really good calculator, everything works good, and is really really fast for huge functions. As a statistics major, im a bit dissapointed, because this calculator is missing alot of the random functions the ti-83 had. Everything else good, great buy.

4-0 out of 5 stars On a voyage.
I've had this calculator for a year and a half and I must say it has served me well. Unfortunately, it just pooped out on me. I tried to use it one morning and it would not come on. All it did since the last time I used it was sit on my desk. No drops or anything. I changed batteries and tried all the troubleshooting suggestions on TI's website. Still nothing. I'm still waiting for a response to my emails that I sent two days ago to the TI Cares support.
This thing was great while it lasted but now it looks like I'll have to get another one or maybe that newfangled TI-89 Titanium with the keyboard attachment.

5-0 out of 5 stars Best calculator when you are on move
I had long been an HP fan but Voyage change my perception about TI. When you use graphing calculator you don't need RPN notation. Voyage is one of the best calculator, with its large LCD screen and Qwerty keyboard you have much ease of entering any equation and it appears in the text book form. It does 2D polar plots, parametric plots, Direction fields and can plot in 3D besides solving differential equations of 1st and 2nd order. However its better to use Maple or Mathematica for 3D plots as they are much faster. It also has preloaded Statistics Package so it can do things like Hypothesis testing fot z test, t test, two sample test, chi square, Anova etc. An engineering package for Osculating circles, Rienmann sum, Curl, Divergence etc is also there, though I didn't find it of much help. However it has better algorithm than maple and mathematica for Double and Triple Integrals. If you are taking linear algebra then you can do things like eigen vectors and LU decomposition too, and with programming you can get Jacobian forms also. Good for Calc-I-II-III, Advanced Calculus and Dfeq.Upgrading software is a breeze with link cable and you have a access to a good application programs from TI to suit your need. Overall the calculator is neat, very intutive. It comes with a thin manual because you really don't need it.For other stuff you can visit their website or use the CD to look for any specific function

5-0 out of 5 stars A great product
The voyage 200 is the finest calculator that I have ever had. Its performance is remarkable and it is a user-friendly product. You do not have to remember in which button is the function that you need, or deal with buttons that have impressed three or more function in different colors. Just type the function and that is it. That is simple, is not it?

It is also outstanding the main menu and its easy navigation. You can customize it by adding software applications from the texas instruments web page. The "Computer Algebra" application can solve equations, integrals and much more. "Organizer" mades a nice calendar to schedule activities, classes, and keep track of the important business of you life. "Notefolio" and "Cell sheet" are applications that work as interface for text and data between calculator and computer.

The operative system can be downloaded to the calculator via USB cable with out problems. In conclusion, I believe that is a great product. Just be careful, so many features are not allowed in most of the standardized test and courses. ... Read more

1-0 out of 5 stars Not a real HP

I bought this calculator because I was afraid to lose my HP-15C while traveling.

I really dont like the calculator because the butttons are oddly shaped and as a result they are difficult to press.Great action on the buttons is a hallmark of great HPs (15, 48, 11, 32, 42 ...)

In addition the screen is difficult to read.

I was glad when mine finally died for some unknown reason.I mailed it back to HPs CEO and she was fired the next week.So... maybe my letter had some effect.

4-0 out of 5 stars HP 33s is on track but could use some improvement
As an engineer, I can see the problems that HP is having in the marketplace with its calculator line.The desktop computer and math software has taken a big slice out of the top end calculator market, and what is nice about the HP 33s is that its positioned as a professional tool that can be used when more complicated math applications aren't needed.I have sold my older 48g and 49g models and don't plan on replacing them.

My impressions of the 33s is that it is a good calculator.Most of the functions are very intuitive and the keys have a nice crisy feel to them.The sweeping keyboard pattern is very distinctive and the calculator itself is light but has a solid feel.However, the display can be difficult to read and the stack is limited to 4 lines.I am not sure how many lines the 32sII has, but it can't be any less and that calculator came out 20 years ago.Overall, I am happy with my purchase.

2-0 out of 5 stars Disappointing Calculator
I have used HP calculators since the very beginning in the early 70's.They were always the top scientific calculators until the early 90's.The best calculator for some time has been the TI-89.

However, what strikes me about the HP 33S despite the difference in appearance and extra capabilities is how much it is like the old HP 15C which was a great calculator when it came out in the early 1980's.I am convinced that this calculator uses much of the same architecture as the HP 15C.I think they used the 15C design and simply made improvements.

This is the problem with HP.I do not think they have been serious about calculator design for years.The HP 48 had serious design deficiencies (it was a lousy programming caclulator) and went for years without improvement.In fact the HP 42 of the late 80's was in many ways superior as a scientific calculator to this (the 33S), but for some reason was dropped.

I could go on for pages about the deficiencies of the 33S but basically I think it is obsolete.It has good qualities but it simply is not much more than the HP 15C of twenty years ago.Personally, I am finished with HP calculators.Unless they recommit to calculators in a serious manner, I regard them as history.

4-0 out of 5 stars Room for Improvement
Don't like: (1) calculator buttons that click, (2) tiny decimal point, and (3) memorizing correction procedures for built-in HP errors caused by deficient quality control.

After taking into account the above listed problems, the HP 33s is superior to TI-36X & Sharp EL-546V & Casio fx-115MS and is one of only a few calculators allowed with NCEES exams.

I have owned various HP scientific and business calculators, including 28s, and the 33s is a couple steps down.Someday HP may regret neglecting what they once did better than any other company on the planet -- designing quality calculators.

4-0 out of 5 stars Lighten up you Hater-Nerd-Milos out there!
I was very nervous making this purchase.Unneccesarily so...the HP-33s is a good calculator with terrific value.The engineers and scientists who have applied their robust intellects at reviling this product are over-doing it.The small decimal point is indeed an issue, but as another reviewer pointed out, just use fixed-point notation and you'll be fine.If you can't see it, you're not working/studying in an environment with enough light. So do something about it, don't blame the calculator.This flaw should not deter anyone from purchasing this calculator, are anal-retentive and stubbornly and childishly fuss about details.Not saying it's wrong to be that way...just know yourself...if you're like that, then the decimal point issue will bug don't buy it.Seriously people, how many times are you going to be working with the number 2,222,222.2222?As for complaints about accuracy when working with complex numbers and random number generation etc...I only have an engineer's background in mathematics, but I know not to do hard-core calcs with a mere calculator, even an HP.If it's your final project or thesis, use a computer with Mathmatica or Excel or MATLAB.For people like me (studying for the PE), this calculator is a fresh update from the 32SII. HP could have done better, but didn't do THAT bad.I think some reviewers with a noticeably left brain tendency are focusing some frustration from their social lives on this poor innocent calculator. I would have reversed the direction of the that the 'V' shape was pointing toward the display, not down toward you.This better matches the natural configuration of your hands. It's well-built and lighter.It looks sexy...the same people complaining about the design are out of touch with current design trends and aesthetics...they've been trapped in the basements of post-mondernist, utilitarian technical schools or companies and haven't cracked a copy of Wallpaper* magazine or seen the latest line of Infiniti luxury automobiles.This calculator takes a step closer to being GUCCI and a step away from being GRANDPA.So much complaining about the colors...this is from people that probably haven't bought a fresh tie in years.A chick in the library or coffee shop might actually come over and pick it up and start talking to me. The signature HP characteristics are there:RPN capable (algebraic is bonus, but not really needed for me), clicking keys that offer clear assurances of crisp, definite key strokes, powerful features that attempt to meet the needs of everyday engineers, scientists and other technical practioners.They're trying to meet the requirements of a wide range of users. Of course, not any one group will be happy.The endless whining over the location of things like the ENTER button shows the silliness of some of the reviewers.How much complaining do people do when they buy a new cellphone and the menu button is different?It's not a big deal because you get a new cellphone like every year, unlike these guys who are probably still using their first calculators.I would have put the ENTER button next to the C button, but then you might accidently clear your registers, doh! At least switch the 0 and the '.' buttons, so that the numbers would match a phone keypad, which we all use and know. Anyone who knows really smart people, knows that they sometimes get worked up over little , nit-noid details.Think the guy from Office Space that was annoyed over the red stapler. If that is the case for you, then drop on a -48GX on ebay for $100, but if you want the 32SII with a new, slick exterior, then the -33S is for you. Don't listen to the haterz!For the record, I'm a HP vet with an -11C, -28S, -32SII, -48GX in my history. ... Read more

3-0 out of 5 stars waste of money
This calculator is a waste of money.If you need a graphing calculator, buy the 83+ or just the plain 84.The 84 is really bulky and not a real improvement on the 83+, the silver edition 84 is even worse - the white looks terrible, and the color face plates are even worse.If you're gonna buy an 84, you should just stick with the regular'll save some money and the blue looks better than the white.You're not getting anything more than what you'd get with the 84.

5-0 out of 5 stars The best i have ever used
This is the best calculator is the best i have ever used. It has a lot of great Apps. it has most of the basics for physics, chem, algebra I & II and a lot more. The keys are also very bright and easy to read. So if u r planning on buying a new graphing calc, go check this this out

5-0 out of 5 stars Wonderful calculator, DON'T BUY A TI83
I got a TI83plus but then it broke. That was probably the luckiest thing that could happen. This calculator is great!! Its fast, its pretty, and its really useful for school. DON'T EVEN LOOK AT THE TI83s BUY A TI-84-Plus Silver Edition Graphing Calculator ITS WORTH THE MONEY!!!!

2-0 out of 5 stars TI-89 Titanium
Ive used this calculator for awhile, then switching to the TI-89 Titanium I realized the TI-89 Titanium is in so many ways better then the TI-84 Plus Silver Edition. The TI-89 Titanium has a Symbolic Math Guide which will show you the answer and the steps it took to solve it. Either get a TI-89 or TI-89 TItanium!

5-0 out of 5 stars I Loved It!!
This calculator is great! If you download some of its applications, it can help you with almost all subjects in high school and some courses in college. You can share information with other calculators and recieve application information. It not only helps you with math courses, but with science and other courses. It's helping me, and it could help you too. ... Read more

2-0 out of 5 stars Terrible Usability, I Don't Like
Nice things about this calculator are it's good looks, simple interface, and price. But, maybe it's just too simple. Personally, I feel this calculator is not pleasant to use.

1. Awkward viewing angle. The LCD is positioned such that you can view it only if your sitting back. Forget about looking straight down while solving problems. You'll be greeted by a terribly dim display.
2. Button response is bad. For a $30 calculator, I expected the buttons to be at least decent. They're not. If you're like me, and are capable of quick entry (sometimes even with 2 hands) and enjoy responsive buttons, you'll be disappointed. The buttons are not firm to the touch and just feel cheap.
3. Lacks slightly more advanced features. While the interface is easy to use and the basic features expected of a financial calculator are there, I think TI has room for some more. For example, there is no Option Pricing feature. That would have been great.

For students (like me) who have worshipped the TI-8x's, the BAII is just horrible to even touch. Nonetheless, most people will find this calculator to be decent, at best. Really, don't expect any surprises, as this is as basic as it gets. For real value, perhaps invest a little more in an HP.

4-0 out of 5 stars A first look at the New Look TIBA2+
BA2+ users may like to know that Texas Instruments has released a "new look" TI BA2+ (allow me to call it it BA2+N), which may come with just more than cosmetic improvements over the popular BA2+.

I was able to observed from a short distant away that the LCD display of the BA2+N,is clearer and more contrasty than the orginal BA2+ which I own. TI gets a thumbs up for doing this improvement quietly plus giving a facelift to this already highly regarded value for money business-financial electronic calculator.

Although I have not yet been able to test the BA2+N, TI may have also incorporated some improvements and killed some bugs on the popular BA2+. It is also probable that some improvements or new functions incorporated on the September 2004 released BA2+ Professional (BA2+PRO) may also have been also incorporated into the specs of BA2+N.

I would like to believe that some small but extremely annoying bugs of the "original" BA2+ has been quietly fixed on the BA2+N. In particular, I wish to see the "Reset" button nuisance which clears all user input formatting on the BA2+ has been done alway with. Most users of BA2+ would know that an accident user soft reset would return to the default Number of Periods per year P/Y to 12, this would upset the results of many TVM calculations when user has set the P/Y to "1" to use the calculator in "number of periods" instead.

I was not able to exam a unit of the BA2+N to see if end users would still need a screw driver to unscrew and pry open the BA2+ casing just to replace the CR2032 battery. It would be nice if TI would incorporate a user accessible slide open battery compartment for the BA2+N or future upgrades of the BA2+.

Would be buyers should get hold of the BA2+N or buy the BA2+PRO if you have a bigger budget. Budget conscious users could see that for the price of a BA2+ PRO, a screw driver and spare batteries, new users could afford to purchase for themselves two sets of BA2+N.

An advantage of having a spare BA2+N set on hand is that users could free themselves from the trouble of carrying a philips screwdriver and replacement lithium batteries to important assignments or to the examination centre.

HOW DIFFERENT DOES THE BA2+N LOOKS? I have downloaded the BA2+N JPEG picture from TI's calculator site and posted it to the Amazon's picture gallery.

IMPORTANT NOTE:I have commented on the BA2+N as an end user and I don't work for TI, HP or any of the manufacturers for the products which I have used, reviewed and posted my comments on the pages of It is my pleasure to be able to share my first look at the BA2+N with you, thanks for reading!

3-0 out of 5 stars CFA users Choose TI BAII Plus
This review is directed toward those taking the CFA exams.The TI BA II plus calculator is more straight forward than the HP 12C for the range of questions asked on the CFA.The BA II Plus calculates faster than the HP, and is less expensive.

If you need the button quality and durablity of the HP 12C unit, upgrade and buy the TI BA II Plus "professional" - this unit has a brushed aluminum case and buttons similar to a HP 12C and costs around $50 - similar to a HP 12C.

When doing uneven cash flow problems the registers to the TI are all labeled so you can quickly enter data giving greater confidence with improved speed to your answers for NPV and IRR calculations.

I still have two or three HP 12C's around, but they aren't as intuitive as the TI for the CFA Exam.If you are taking the exam - the TI is the way to go.

3-0 out of 5 stars man, this thing's annoying
If not for the fact that this calculator is required for the CFA i don't know why anyone would buy it.
It takes many, many keystrokes to get simple things done, and let's face it, in the real world i'd much rather work out a complex NPV calculation in excel where i can see what i'm doing step by step rather than some arcane series of keystrokes where one mispressed key will screw everything up.
Also, my unit suffered from poor battery life, which i assume is a manufacturing defect.
A word of advice for students who can use a more advanced calculator: get a ti-83 or similar, learn to use it, and you'll be much happier. I find myself using the ti-83 i got in college rather than my financial calculator all the time.

2-0 out of 5 stars Easy to make mistakes
I got this calculator free on a financial course I am taking.It is easy to use but what others say about getting wrong answers seems to be down to the operator buttons on the right hand side being out of line with the main keypad.So you have to watch what you are doing.This and the fact it seems to take so many keypresses to get anything done makes it cumbersome.It is a reasonable calculator for starting out but I would not recommend it if you are in a hurry eg. sitting an exam. ...

2-0 out of 5 stars Horrible "feel" and cheap case
The buttons are horrible...I can't tell you how often I have to retype numbers because the calculator did not capture my input.The buttons have a "sticky" feel and are small.Also, the case is a cheap attempt to emulate the strength and durability of the HPs (I hate the 12C...but I think its design and durability has not yet been matched).

3-0 out of 5 stars Slow Input
This is a great calculator, but when you input numbers fast, they do not always register.If you buy this calculator, input 1,2,3,4,5,6,7,8, and 9 as fast as you can.You may encounter some numbers not registering even though you hear the number click (as if the number was added).This was not a problem with the BAII Plus.This is a huge disadvantage to this calculator.

5-0 out of 5 stars Major improvement from BAII Plus
Compared to BAII plus, it is much heavier with the metal cover. Too light is a disadvantage for the old model. Now, this one won't jump around when you punch the keys. The pros of HP 12C says that one is like a tank. This one is just like a samller tank, maybe.

The display is another major improvement. The view is clear and won't change for different angle. This won't be a worry on your CFA exam.

Keys are harder to punch; this is a bad feature for professionals. But it is not that bad as long as you can hear the "click", which is not that hard, the number will be there. People with less strength on their finger will complain too.

Easier to change the battery, though you might worry it is too easy. Don't open the cap too often will help. The good news is you no longer need to carry around a skrew driver on you exam day, only the battery.

4-0 out of 5 stars Great product, cheap case
Just to clarify, this is a financial calculator, essentially the same calculator as the "Texas Instruments BA II Plus Advanced Financial Calculator" but with a cosmetic make-over.

- Very attractive appearance.
- Nice "firm-touch" keypad.
- A couple of additional functions (compared to the BA II Plus Advanced).

- Leatherette soft case instead of hard case.
- Approx. $21 more (at time of writing) than BA II Plus Advanced.

This is a very nice calculator.It is full-featured financial calculator with an attractive appearance.The brushed metal facehas a polished metal inset to highlight the primary financial function buttons. I like the button layout (which is the same on both the Professional and Advanced models), and preferred it over that of the HP 10bII financial calculator, which I thought had poorly-marked non-financial functions.

The calculator has a solid feel that is consistent with its metal look, and that is further reinforced by the "firm-touch" keypad.Personally, I like the feel of the firm-touch keys and prefer it over a regular keypad, as is found on the BA II Plus Advanced.

My one complaint about the BA II Plus Professional (and the reason I rated it as 4 stars instead of 5) is that it has a soft case instead of a hard case. While the soft case will help protect from superficial marring, it won't protect the calculator from impact or pressure damage, or from accidentally pressing buttons (such as "On") when carrying it.For the extra $21 more than the Advanced model, it would be nice if the Professional model came with a case that will actually protect it.

- If you plan to keep your financial calculator around for a while or will use it a lot, and want something nice, then I would recommend this calculator. (I basically think of it as an investment in something I will continue to use for several years.)

- If you think you would prefer a more firm-feeling keypad, then I would recommend this calculator.

- If you are just buying a financial calculator for a finance class and don't plan on getting much use out of it afterward, and don't need the additional functions of the Professional version (which are advertised as being "Net Future Value (NFV), Modified Internal Rate of Return (MIRR), Modified Duration, Payback, and Discount Payback"), then I would recommend saving some bucks and getting the Advanced model of the BA II Plus.

5-0 out of 5 stars Easily better than ANY current HP--and 1/2 the price!
Have been a stalwart HP financial calculator user for over two decades...started with an HP41 in college with financial templates.I always admired HPs for the durable build, ease-of-use (once you got over the RPN hurdle) and displays.I finally needed to replace my over decade old HP 12C and the newer HPs simply do not impress me.Cheaper (as in WAY cheaper!) build...the HPs that came from Malaysia were fantastic calculators...solid keystrokes, superior grade of plastics, the whole nine yards.The newer HPs are made of a plastic that is a giant step backwards.The keys are now laughable, no 'HP Feel' to them at all.

I took all of this in and thought to myself, 'I guess everything is getting cheaper, nowadays...'.Then I ran a NPV calculation at the store and was downright shocked to see it ran slower than my old HP.The one thing I thought MIGHT save the purchase (i.e. cheaper plastic but faster processor) didn't happen.I tried all of the newer HPs...the one display model of the OLDER HP12 (the non-Platinum model and still made in Malaysia) definitely runs TVM calculations quicker.This is NOT how to impress old bankers with a new product.

Time to check out the Texas Instruments BA II Plus Professional.At first glance, to an old HP user, I thought it really LOOKED TI-ish; that is to say, very non-HP.But upon pressing a key or two, I was impressed that TI at least made an attempt at obtaining the old 'HP Feel' to their keys.Not as 'pretty' as HP's angled keys, but good tactile feedback and get this:If you'll hold up the TI BA II PP horizontally and sight down the keys, you'll see they are actually angled!Nice touch, TI.

Nicely laid out TVM section (my only reason for owning a financial calculator, thus supremely important to me) and intuitive to boot.Speed of calculation simply SMOKES current HPs...there is absolutely NO CONTEST.A complex Internal Rate of Return took two to three seconds.TI hasn't been simply sitting around and 'repackaging' anything; whatever is under the hood of this calculator is current and fast.

The rest of the calculator is nicely laid out...keys are pretty much TI convention, which to me is different.I miss a prominent ENTER key.

Likes:I like TI's 'CHAIN' calculation mode.It's similar to RPN without the ENTER keystroke.Remember this if this is your first financial calculator:Most financial calculations are run in CHAIN or RPN mode (and, sadly, no, the TI doesn't support TRUE RPN), not the Algebraic Operation System (AOS).To TI's credit, the calculator defaults to CHAIN calculation (for newbies, this just means that the calculator runs the operation AS IT IS ENTERED; NOT following Algebraic heirarchy of operations).But it is nice that TI recognizes how financial people enter calculations and, unlike other TI calculators, AOS is NOT the default entry mode.

Love the fact that the compounding rate is defaulted to 1, not 12 (HPs always default to 12).Love the fact that interest is always entered as a whole interest number (it divides it for you, automatically).Good, not great, manual.Battery access is very easy.Quality looks genuinely good, but time will be the only final arbiter on this one, but the product appears to be (in my highest compliment) equal to older HPs in every respect.

Dislikes?Quibbling ones to be sure, but the compounding rate mentioned above is a pain to get too; I must have looked 30 minutes in the manual to finally find it (hint: you have to use the Down Arrow key to roll through a series of selections to get it...and it's NOT the first choice).Wish for (on all financial calculators, not just TI) normal AA or AAA batteries...why the manufacturers have to insist on the round, hearing aid style battery is beyond me.I mean, really, how big is a AAA battery?

Wish TI would step up to the plate and offer some mortgage/realty functions in a financial calculator without forcing a user to own 2 calculators.Wish it were programmable, which is just a follow-on to the mortgage/realty/specialized functions.

If TI offered this same model with enhanced functions, programmability and a normal battery, HP could give up the calculator market.

As it stands, a worthy heir to the older HP calculators.I'm sorry to see HP cheapen the product so badly, but TI will gain market share on this one.A solid keeper. ... Read more

4-0 out of 5 stars less is more.
I am on my third TI-83+ (my first two were stolen).My brother owns an 84, and I can tell you that it offers nothing that the 83 doesn't have.Many of the preloaded apps are useless (an address book?please!), and take up so much space that the memory increase is worthless.The 84 is a continuation of TI's tendency to offer huge amounts of style with little or no substance.I prefer the 83 for its streamlined design.The one improvement is that the slip cover on the 84 does not become loose with a great deal of use, which is a problem I have encountered with my three 83s.It looks as though the USB connectivity could be a plus (for the 83, you had to buy a separate connectivity kit to connect to a PC), however, most buyers will not need to connect their calculator to their PC.

5-0 out of 5 stars VERY helpful!
Since I am in the higher math, I really needed a graphing calculator. So we saved up some money and got this.... and it helps so much! I don't really have anything to compare it too.... it is good for people in algebra and up though. and just fun to mess around with :D

5-0 out of 5 stars Best School Supply Ever!
This calculator is hands-down the best I have ever had the honor of using. While the TI-84 Plus may not have as much space or as many pre-loaded Apps as the TI-84 Plus Silver Edition, the TI-84 Plus offers everything a high school (possibly some college) math student needs in order to successfully learn and solve mathematics material. The TI-84 Plus comes loaded with several Apps that will make things even more convenient, such as a Probability Simulator and Cabri Jr., a great geometry app. Student looking to upgrade from the TI-83 Plus will find comfort in the fact that the TI-84 Plus is 2.5x faster and has 3x the memory than the TI-83 Plus. The TI-84 Plus is also extremely easy to hook up to your computer to transfer new Apps and updates to it using the USB port and the included USB cable. The TI-84 Plus will be a great investment for any student's education.

5-0 out of 5 stars A great improvement on the TI-83 Plus
The new TI-84 Plus is a wonderful calculator.If anybody has had the TI-83 or 83 Plus, they know how easy and reliable it is.The 84 Plus is an all-around imprivement on the older version and even worth the additional $15-$20.I have had it since school started and have noticed than any problem I enter, it is solved immediately upon pressing enter, or solve.The speed is a great improvement over the 83-Plus.The computer features are nice, but rarely used by myself.For anybody who is supposed to buy a TI series calculator for school, the 84 Plus us definitely the one to pick up this year and for the next few years I assume.Easy, fast, reliable, durable, and even sleek.As long as you handle it properly and use it enough, you will get all of your $110 out of the TI-84 Plus.

1-0 out of 5 stars DIFFICULT TO USE!

4-0 out of 5 stars Excellent but user unfriendly
THis machine does it all provided that you learn how to use it well. I spent quite some time on this calculator and I am very confident using it now. However it could have been more user friendly.

5-0 out of 5 stars DO NOT BUY unless you are in calculus
PUBLIC SERVICE ANNOUNCEMENT:This is a fabulous calculator (thus the five star rating), but inappropriate for students in math below calculus.Below calc, most courses that require a graphing calculator are geared towards the 83/84, so unless you are very comfortable with the 89 it may prove difficult to translate in-class activities onto an 89.Do not even THINK about buying this calculator unless you are taking calculus or a calculus-based course.Stick with the 83/84.

5-0 out of 5 stars Sweet Calculator (For Calculus ETC)
Awesome calculator. Last class I used it for was Calculus for Engineering I. I like the "pretty print" which will display equations exactly as you would right them. The calculus tools, and the resolution of the screen, and the ability to scroll through previous equations.

My favorite T1 so far that I've used.

5-0 out of 5 stars Essential for Calculus and beyond
Once the essentials are learned in any field, its great to have a tool to do the busy work quickly.The Ti-89 calculator by Texas Instruments performs all the functions you'll need to do this busy work.Being able to use SmartText to display integrals, differentials, taylor series sums, etc. allow the user to clearly identify any mistakes.A lot of technology has been pumped into this little machine seeing as calculator programs are written using only the functions +-/X.There are many submenus's withen keys that are color coded for easy recognition as well as on-screen displays for menus.Dual menus are also handy for comparing graphs and calculations.Programming is a sinch with the instuction book and downloading programs is possible with the add-on cable.There are thousands upon thousands of programs written for math, economics, accounting, etc. that will allow the user to drastically expand the functionality of this calculator.5 Stars.

5-0 out of 5 stars Great Calculator
I bought this calculator after having used a TI-83+ for a few years. The power in this little machine is incredible (and in fact uses the same processor as the Macintosh Classic computer from 1991) and the display resolution is fabulous, especially compared to the older calculators. While I have yet to use some of its more advanced functions, the ones I've used have been great. Some of the functions from the TI-83 are moved and take a bit of adapting, but after a few weeks you'll love the menus so much you'll never want to use a TI-83 (or a regular scientific calculator) again. ...

5-0 out of 5 stars Fantastic product
Despite the over-zealous negative reviews, I ordered this calculator and couldn't be happier!!! (I wonder if they work for the competition?)

I am a business school student and originally started with the TI BA2 Plus, but was terribly disappointed, so I switched to a HP calculator based on the recommendation of two professors...I am so pleased that I did!

This is a solid device and has not failed me in doing complex financial calculations.This is simply the best calculator I have used and I encourage anyone looking for a workhorse capable of doing long, intense calculations to buy it immediately!You won't be disappointed.

3-0 out of 5 stars One more gripe
Other reviewers have pointed out ways in which the 12cp falls short of the original 12c, so I won't repeat those.My gripe is that the case for the 12cp is complete crap.It's stiff and horrible.It takes considerable force to stuff the calculator into the case, whereas the old 12c case fits like a custom glove.

1-0 out of 5 stars Very Disappointing....
At first glance, this thing looks great.Nice, updated design, amdthe color looks good.But then there is the Enter key "bounce."The orange function lettering is almost impossible to read.Some of the TVM calculations are slower.

It's great that they made the numbers on the display larger, but the display itself is DIMMER!Much harder to read in certain light conditions than the 12C.What were they thinking when they designed this thing???

For $19.95 this device would be a good buy.But not at the $80 that I paid before I returned it.

Do yourself a favor.Pass this one by and get the good, ol' 12C

4-0 out of 5 stars 12C Platinum is Great!
12C Platinum is way better than what the reviews say.It's classy looking and has RPN AND algebraic.My kid brother, who isn't too RPN, is already borrowing this.I keep stealing it back for its RPN features.HPjust needs to have these at the stores so that more people can view it, try it and buy it!

5-0 out of 5 stars This calculator will last forever!
I bought my Casio CFX-9850GB Plus in 6th grade for Pre-Alg. and I'm now in 11th grade AP Calc, and my calc. still works like it did 5 years ago. The color screen is a life-saver when graphing multiple ftns. or just for something pretty to look at. It's equation solver is great for tests, and the easy-to-use menu is much better than that of the TI-graphing calcs. Also, it has been in my backpack for years, and I drop it almost daily, but it hasn't affected its performance at all. At $70, this is a bargain, and it may just be the last graphing calculator you'll ever need!

5-0 out of 5 stars Beats the TI-83
I am a math teacher at a new private Bronx high school, and compared the TI-83 with the Casio in numerous regards before deciding which one our school would use. Hands down, the Casio wins, and it is cheaper as well. Note - I do not work for Casio or TI.
A) The calculator is more user friendly. The options are menu driven in a more intuitive way. What took me a minute or two to locate and figure out out the TI, took less than half the time on the Casio. Don't trust me- see for yourself.
B) The Casio is slightly faster than the TI
C)Features: The casio adds a dynamic graphing system (lets you change a coefficient and watch the graph change), which is very useful when teaching. I also like the EQUA feature, which lets my students calculate 2/3 equations, 2/3 unknowns, and solve quadratic or polynomial equations. Maybe the TI does this too, but I couln't figure it out.
D) The color thing I suppose is nice, but I use the CFX-9750, which is black and white and cheaper.

The only downside is that most colleges use the TI's, unfortunately. I liken it to most places using Microsoft when there are better alternatives out there (monopoly power). Anyway, a student who uses the Casio can do anything the TI-83 can do.
I'm a big fan, and my students seem to like it.

3-0 out of 5 stars CASIO -- "The Unexpected Extra®"
The Unexpected Extra is the cost of the computer cable and software (an optional extra purchase). It's nearly equal to the price of the calculator. That adds up to roughly the same price as the far more advanced TI-89 Titanium kit with cable and software included.

5-0 out of 5 stars A real babe magnet
Ive had this calculator for a year and it is a testiment that something can be attractive and geniusly engineerd. Never have i recieved such complinents for owning a calculator. It makes the texus instruments look like typewriters the technology is so much better. People come up to me and want to play with it, and i say, "Yes ladies... its a casio." Truley an ingenius tool.

5-0 out of 5 stars Great Calculator
I bought this calculator before i enetered the 9th grade.Everyone in my class had the Texas Instruments TI 83 so i wanted to be different so i bought the CFX-9850GB Plus.It was the best desicion of my mathemtics life.Aftewr my friends saw the features and the user friendly menu they also decided to buy one.It has more features than the TI 83 and is easier to use.It is a bargain at the price it is being offered at.Even if you already have a graphing calculator i suggest buying one ASAP. ...

For the book lover who thought they had everything, this may be the perfect gift: a dictionary that draws its 130,000 definitions from the American Heritage Dictionary (4th edition) and is small enough to serve as a bookmark. The Zelco Bookmark Dictionary II’s ultra-thin, flexible keyboard pad clips onto the page of a book for easy reference. Other functions include a measurement converter and a calculator. Date and time are kept with an internal clock.

The keyboard features slightly raised touch buttons, with additional, alternate key functions that operate during calculator mode. The LED screen features relatively 1/2-inch-tall figures for easy reading. When the dictionary is clipped to a page as a bookmark, the screen sits above the book.

Use a small Phillips-head screwdriver to change the CR2032 3-volt lithium battery. The Zelco Bookmark Dictionary II measures 3-3/4 by 5-3/4 inches, while the display screen at the top is 3-3/4 by 1-1/2 by 1/2 inches. Zelco offers a one-year limited warranty covering defects in materials and labor that occur during normal use. --Garland Withers ... Read more

2-0 out of 5 stars Still going to look
I received this as a gift for Christmas and I have two main complaints.First, and more important, I would say 1/3 of the words I look up are not in this product.I have a decent vocabulary, but I'm no lexicographer, and it's frustrating not to find so many words.The second complaint is that the buttons are difficult to push and I wish the product would default to "dictionary mode" when I turn it on, rather than always have to push an extra button to get there.It is a dictionary after all--why would I buy this if I really wanted a calculator?It's a nice feature, but bury that somewhere else and make it easy for me to look up my word without having to push extra buttons (which are hard to push!)I'm sure there's something better out I'm off to find it.

1-0 out of 5 stars Looks too much like version 1
Version One's story:

I thought this bookmark would be a great idea.Having a dictionary at the palm of my reading material was a great idea, so I made an impulse buy with this product.Here are the problems and annoyances I have with this product:

*Not enough obscure words in its dictionary
*It's a pain to type these words on the small keypad
*Bookmark is top heavy and which makes it awkward.It would be much better if the whole bookmark was close to paper thin.

So, sadly, the product is pointless.I wouldn't waste your time with version II either, I am sure the same complaints apply.

1-0 out of 5 stars Looks like a waste of money
after reading 2 negatives on this contraption, I don't see the need to waste my money on a electronic toy that does not work.

I would rather buy a CD and load it into my computer from an American company any time.

4-0 out of 5 stars Excellent word tool
This is a very useful device for the avid reader! It is thin, easy to use, and by far the most convenient dictionary around. It fits on a book jacket and is ready for any new words that pop up while reading. Range of words is extensive - only a few words looked up that not in it so far in use for over a two months.

It has been well received by my teenagers - saves having to jump up to fetch yet a another book. Particularly useful in travel situations like an airplane or a car trip where toting around a standard dictionary is impractical.

Only draw back (and reason for a one-star deduction) is that it requires reflected light, which makes the text a tad it difficult to read when in low light situations.Could be enhanced with a small backlight feature - maybe in version III.

Definitely recommended. No problem with functionality mentioned by another reviewer.

1-0 out of 5 stars Not recommended!
I received this bookmark dictionary 2 weeks ago, and it's already broken!The upper left portion of the key pad has stopped working, and the buttons that actually do work need to be pressed hard in order for the letter to register!I definitely DO NOT recommend this item. ... Read more

1-0 out of 5 stars why not get a HP49g+? Look at the price!
at the time of writing the HP49g+ is available on
amazon at $77.99. Since the 48GII is a 49g+ with
features removed - why not get a 49g+ ?

3-0 out of 5 stars Hold on to your 48GXs
I had high hopes of this calculator being a "real" 48G, maybe with a faster processor running an EMU, but the original case/key design and ROM.

My trusty HP48GX no longer functions properly, the 3, 6, and 9 keys fail to register when pressed.

Bill Hewlett and Dave Packard would join me in my sadness and disappointment at the lack of innovation at HP, and the pathetic replacements offered to the fine 48GX, the lowly, rubber keyed, algebraic entry, plastic faced, 49G and 48GII (both of which I have tried and rejected).

Upon inquiry to HP customer support about the possibility of getting a 48GX repaired, it became apparent that the cheap printers they make, Carly's merger with Compaq, and Hewlett Jr.'s denouncement of the company's current direction are indicative of the level of service and quality of customer support technicians hired by HP, [...]
While searching for a replacement for my 48GX, I encountered a strange phenomenon, used HP48GXs are selling for twice what the new flagship HP calculator costs, and as much as $400-$900 for the few unused 48GXs still around.This is a testament to the failure of HP to continue to provide innovative products, and to the brilliance of the engineers and programmers of the original 48GX at the now defunct Corvallis research facility.

How can a nearly 15 year old technology product still remain the most desirable and sought after in it's class?Only through initial brilliance coupled with the failure of executive management to develop and support the innovation required to improve such a product rather than trying to replace it with a lesser machine.What right-minded consumer would purchase a 49 to replace a 48?

Alas, we have witnessed the demise of the only truly innovative producer of engineering calculators.What does the slogan "HP Invent" mean today?

The talent behind the last several 48G ROMs, Jean-Yves Avenard and Gerald Squelart have given me renewed faith in the future of calculators. After being fired by the new HP, they have taken it upon their selves to create the finest calculator in the world, the Qonos, and I eagerly await it's release. [...]

In the meantime, I am about to embark upon an all-or-nothing attempt to service my own HP, a process which involves a drill press, razor blades, and surgical precision in hopes of extending it's life once again.

Good luck, and protect your HP from cheap batteries and wrong-doers at all costs.

5-0 out of 5 stars Yardstick for Calculators
I must admit that I am loyal to HP calculators! I bought the HP35 in the early 70's when I was a graduate student at Washington University. I currently collect HP calculators.

When I bought the HP 48gII about a month ago I encounted the much talked about keyboard problem. I did what comes naturally. I called customer service. A very friendly representative took my name, address, and the model and serial number of the problem calculator. In about 30 seconds I was informed that a problem free calculator would be on the the way in 3 to 5 business days! I was also given a case number so that I could keep tabs on the progress of the shipment of the replacement. Note that I did not ask for a replacement! The company apparently is on top of the problem and know exactly which calculators need replacement. I asked about instructions for returning the problemcalculator and was told to wait for further instruction from HP. If I do not hear from HP in 30 days, I may dispose of the problem calculator as I see fit. What else could one hope for?

In four business days I received my new HP48gII with three 3AAA cells and two memory cells. The calculator only reguires one memory cell. I immediately checked out the calculator. My problem calculator would ocassionally not respond to the pressing of the up/down and left/right keys. At times others would not respond. With the new calculator I have not experienced any problems.

Go on. Stop listening to the foolishness. Get the best calculator out there. Get the HP48gII!

5-0 out of 5 stars H(P)ope Springs Eternal
Hughey-Pack is baaack!(Okay, tone it down a bit.)No, I really like the new 48gII, although I can't figure why they chose to ID it in the 48 series, since it clearly is a derated 49g+, itself a nice update of the original 49g. I guess 49g- didn't sound too upbeat.And why the serial port when the 49g+ has USB? My laptop doesn't have serial, so I'll have to front thirty for a USB serial converter anyhow. So, in retro, I should have sprung the extra forty dollars for a 49g+, and I've answered my own question. But this clearly brings HP back in line with the TI89. I bought an 89 last spring at Wallyworld for sixty dollars unopened (I guess they were clearing them out for the Titaniums: even so, my fellow engineers called me "traitor", but, hey, sixty!) I was impressed by the Derive CAS and the overall physical quality. Compared with my 49g, it symbolically integrated ordinary expressions quite fast. The 48gII puts HP back in this league, with the (I'm guessing) Erable CAS and 48 MHz CPU.TI quality has improved markedly in the last few years (it had a long way to go) and HP's has slipped some, but the HP48gII seems solid, although it just doesn't have the heft and feel of my fourteen year old 48SX (which still works perfectly with Sparcom Calculus card and all.)No keyboard problems so far, but then no display problems with my TI89 so far either , just waiting for the shoe to drop.

Products like this are what keep HP a quasi-religion for most engineers: my original HP35 , thirty two years old, still works sans battery pack, although watching it canoodle for a full second to extract the sine of PI/6 is amusing, we've come a long way. I always thought HP should have marketed a version of the HP95 palmtop with MathCad or TK Solver in ROM forscientific/engineering folks.And Carly should take a look at the Qonos on, and maybe goose the ACO: tech types would line up like Matrix first-nighters, four hundred in hand, for something like this with the HP sticker.

3-0 out of 5 stars Hope they've fixed the keyboard (updated Oct 04)
I bought this calculator a few months ago.Used to use a 42s, as well as 32 versions.I haven't had any trouble adapting to the new enter-key location, and after spending some time studying this more complicated computing device, I sort of like many of the features.However, the keyboard on mine is unacceptable.As others have commented (both here and on the page for the 49g+), the keys will sometimes miss the keystroke.I find this totally unacceptable, and I, like others lament the decline of quality in HP (at least in the calculator arena).But, I'm hooked on RPN and TI doesn't have it.I plan to try to return my 48gii to HP and see if they have actually fixed the problem (some reviews of the 49+ look hopeful in this regard).If you have a newer model and the keyboard works perfectly (which it should), please post here so we can once again get people buying HP calculators!It will do us all good ;-)***OK - I called HP support.They were very nice and sent me a new calculator.The calculator had an earlier serial than the one I already had - so I wasn't hopeful, despite what they told me.Sure enough, it acted about the same.HOWEVER:1)This was a couple of months ago, so it is possible manufacturing has improved in the mean time.2) I have found a good workaround:Turn on the keystroke beep sound.It's not too loud, does not bother me, and most important, it is very obvious now when it misses a keystroke.I don't have to look at the display - which slows down work.Instead, my senses detect the missing beep without even thinking and I then just hit the key again.I strongly recommend this for anyone with an existing calculator with the problem - and am hopeful based on some recent reviews that HP may finally have fixed the issue on the latest ones being produced... ...
